Description

一种改进损耗的传输线 A transmission line losses Improvement

技术领域 FIELD

[0001] 本发明涉手机天线的设计技术领域,尤其涉及一种改进损耗的传输线。 [0001] The design involving mobile phone antenna Technical Field The present invention relates to transmission line losses in particular to an improved.

背景技术 Background technique

[0002] 天线是一种利用频率特性接收和发射信号的装置。 [0002] The frequency characteristic of the antenna is a device to receive and transmit signals using. 近年来,用于无线通信的移动终端天线的设计和性能,越来越影响移动通信的发展方向。 In recent years, the design and performance of a mobile terminal for a wireless communication antenna, increasingly influence the direction of mobile communications. 特别是便携式移动终端如手机,PDA (Personal Digital Assistance),MP3/MP4。 Especially in portable terminals such as mobile phones, PDA (Personal Digital Assistance), MP3 / MP4. 天线设计的几个主要指标是:有合适的多频谐振,天线实现信号传播和能量辐射均基于某个频率的谐振。 The major parameters of the antenna design are: a suitable multi-frequency resonance, and an antenna for signal propagation energy radiation are based on a resonant frequency. 如果一个天线能在多个频率都能谐振,那么天线将可以在多个频率工作。 If one antenna can be able to resonate at multiple frequencies, then the antenna will be able to work at multiple frequencies.

[0003] 近年来,越来越多无线终端采用低剖面的结构设计。 [0003] In recent years, low profile design of more and more wireless terminals use. 也就是终端的厚度越来越小,“薄”是很多手机追求的目标。 The thickness of the terminal is getting smaller and smaller, "thin" is a lot of mobile phones goal. 为了达到这一目标,很多手机采用了分立式的PCB板设计,即采用两块PCB板分别位于手机的两端,我们可以用主板指其中的一块,上面通常有射频模块,小板指另外一块,上面有一些简单的连接和匹配电路,小板上方通常是天线的。 To achieve this goal, the phone uses a number of discrete PCB design, i.e. using two plates located at both ends of the phone PCB, we can refer to a motherboard which, usually above the RF module, the small plate means further a, above some simple connections and matching circuit board side is generally small antenna. 一根直径很细的同轴线连接小板和主板,用来把射频信号从主板引导到小板上。 A very small diameter of the small coaxial connector board and the motherboard, for guiding a radio frequency signal from the main board to a small plate. 同轴线的直径越小,单位长度上的损耗越大。 The smaller the diameter of the coaxial line, the greater the loss per unit length. 但是,因为手机的空间集成度越来越高,要求使用尽可能小直径的同轴线,这和减小损耗正好是矛盾的。 However, because the space integration of mobile phones more and more, requires the use of small diameter coaxial as possible, and to reduce the losses which happens to be contradictory. 如何在不增加损耗的情况下,尽可能的减小这一段同轴线所占用的空间,是我们面临的挑战。 How without increasing losses, as much as possible to reduce the space occupied by this section of coaxial line, is the challenge we face. 近年来,用微带线来实现传输线是一个可能的选择。 In recent years, with the microstrip transmission line is to achieve a possible choice. 但是微带线是一个对信号而言半开放的结构,信号的屏蔽性有问题,容易产生信号的干扰。 However, the microstrip line is a signal in terms of a semi-open configuration, the shield of the signals in question, prone to interference signals. 用带状线结构来实现的传输线是一个不错的选择。 Strip line transmission line structures to achieve a good choice. 信号线位于两层地的中间,信号得到了很好的屏蔽,不容易产生干扰。 Intermediate signal lines of the two layers, signals are well shielded, not prone to interference. 另一方面,为了射频性能和制造的稳定性,信号线的宽度一般不要小于0.1毫米。 On the other hand, in order to manufacture the RF performance and stability of the width of the signal line is usually not less than 0.1 mm. 这就对带状线的厚度有一定的要求。 This requires a certain thickness of the stripline. 同时,带状线、微带线等传输线均依赖至少一层的介质与至少一层信号线的压合,而介质和信号线不能直接压合,必然会出现至少一层粘胶性质的粘接层。 Meanwhile, stripline, microstrip transmission lines, etc. are dependent on at least one of the medium and the at least one signal line of the nip, the dielectric and the signal line can not be directly pressed, at least one layer of adhesive bound to the adhesive properties Floor. 由于粘接材料的相对介电常数和损耗角比较高,这一现象在高频段,例如3Ghz以上表现的尤为明显,从而导致传输线的插入损耗在高频段变得恶化。 Since the relative permittivity of the adhesive material and the loss angle is relatively high, this phenomenon at a high frequency, for example more especially 3Ghz performance, resulting in the transmission line insertion loss becomes deteriorated at high frequencies.

[0004] 附图1-2为现有技术的示意图,图1中10为传输线,11和12为传输线50欧姆的接头部分,与手机等移动终端50欧姆等阻抗器件相连。 [0004] FIG. 1-2 is a schematic diagram of the prior art, FIG. 1 is a transmission lines 10, 11 and 12 ohm transmission line connector portion 50 connected to the mobile phones and other mobile terminals 50 ohm impedance device and the like. 13为传输线除接头11、12的局部传输部分,13-1为正视图,13-2为侧视图。 13 is a partial transmission section 11 of transmission lines other connector 13-1 is a front view, a side view 13-2. 从13-2中可看出现有技术的粘胶层完整地盖过信号线并与信号线21存在重合,由于粘胶具有流动的特性,通过粘胶和信号线的挤压使信号线完全埋入粘胶之中。 13-2 As can be seen from the prior art adhesive layer completely overshadowed by the presence of a signal line and coincides with the signal line 21, since the adhesive has fluidity properties, by extrusion of the viscose and the signal line is completely buried in the signal line among the glue. 图2为无过孔的传输线,粘胶结构与图1相同。 FIG 2 is a non-through hole of the transmission lines, the same configuration viscose FIG. 由于粘胶直接覆盖信号线,粘胶的损耗角直接影响信号线的插入损耗,从而造成传输线的插入损耗增加。 Since the signal line directly covered viscose, viscose loss angle directly affects the insertion loss of the signal lines, resulting in increased insertion loss of the transmission line.

[0042] 在本实施例中,传输部分13的上、下两层外表面上还设置有保护层24、25,保护层采用抗氧化绝缘性材料,如油墨等,起到防止传输线氧化,以及绝缘的效果。 [0042] In the present embodiment, the transmission portion 13 of the upper and lower layers on the outer surface 24, 25 is also provided with a protective layer, the protective layer is made of oxidation-resistant insulating material, such as ink or the like, serves to prevent oxidation of the transmission line, and the effect of insulation. 具体的,保护层25、24分别设置于信号地层28、29的外表面上,且保护层25、24分别与信号地层28、29相粘接。 Specifically, the protective layers 25, 24 are disposed on the outer surface of the signal layer 28, 29, 25, 24 and 28, 29 are bonded to the signals in the formation protection layer.

[0043] 具体的,介质层26、27与信号芯21之间通过粘结结构22相粘接。 [0043] Specifically, the structure 22 by bonding adhesive 21 between the dielectric layers 26 and 27 and the signal core. 在本实施例中,粘结结构包括相互独立且分别位于信号芯21水平方向两侧的粘接部分22,且两粘接部分22与信号芯21之间相互隔开形成第二间隙30 ;两侧的粘接部分之间还设置有若干粘接桥31,若干粘接桥31穿过信号芯21,并与信号芯21相交,且粘接桥31连接信号芯21两侧的两粘结部分;若干粘接桥31与信号芯21相交处相间隔开,形成若干周期性间隙,如图3所示。 In the present embodiment, the bonding structure comprising mutually independent and respectively located on both sides of the adhesive core 21 in the horizontal direction of the signal portion 22, and the two adhesive portions 22 and 21 between the signal wires spaced apart a second gap 30 is formed; two an adhesive portion provided between the side of the bridge a number of adhesive 31, the bridge 31 through a plurality of signal bonding the core 21, core 21 and intersects the signal, and the two adhesive portions 31 on both sides of a signal connection 21 of the core adhesive bridge ; a plurality of spaced apart bonding bridge 31 and signal 21 at the intersection of the core, a plurality of periodic gaps are formed, as shown in FIG. 在压合过程中,由于粘胶的流动性,同现有技术一样,信号芯21会埋入粘接桥31与其相交的部分,但由于周期性间隙,信号芯21周期性地部分埋入粘接桥31。 In the pressing process, the fluidity of the adhesive, as with the prior art, the signal 21 will be buried in the core portion 31 intersects an adhesive bridge, but due to the periodic interval, the signal core 21 partially embedded in adhesive periodically bridging 31. 同时,由于压合的温度和真空处理,处于周期性间隙中的信号芯21与介质层26、27将会在真空处理下紧密结合在一起,这样减少了粘接材料与信号芯的接触,从而使得粘接材料对信号芯21的影响减小,传输信号的插入损耗也降低了。 Meanwhile, since the temperature and vacuum pressing process, the dielectric layers 26 and 27 at 21 will be close together in the vacuum processing signals periodically core gap, thus reducing the adhesive material in contact with the signal core so such that the adhesive material effect on the signal core 21 is reduced, the insertion loss of the transmission signal is reduced.
